233 GEOLOGICAL RECONNOISSANCE 
mines are in township 3 north, range 11 west, and about ten miles north 
of Little Rock. When first discovered, these mines created considerable 
excitement, and the right of mining was leased by the proprietor of the 
land, My. Kellogg, to a company, who were to hold this right so long as 
they paid him regularly a stipulated amount of the ore. Some forty or 
fifty tous of this ore were mined and shipped to Europe, for the purpose 
of ascertaining its value. No account was ever received, at the mines, 
regarding the sale or disposition of this shipment of ore; and the company, 
whose means were limited, becoming involved in debt and discouraged, 
finally abandoned the enterprise. 
From long disuse, the shafts from which this ore was raised, have 
become filled with water, rubbish, earth and rocks, washed in or detached 
from the mouth of the pits,so that there is no opportunity, now, of inspect- 
ing the condition of the ore in place. In giving an opinion, therefore, in 
regard to these mines, we have to judge from the material thrown out, 
from the general geological structure of the country, and from information 
derived from Mr. John W. Purdom, who lived close by the mines at the 
time the ore was mined. It appears that the ore was found, not in a 
single vein only, but occupying a number of veins, which traverse the 
argillaveous shales under the millstone grit at this place; these seem to 
have very much the same distribution and relation, as those previously 
mentioned as occurring on the property of Dr. Lewis, at the Bull moun- 
tain, in the north-east part of Conway county, as well as those observed 
near Mr. Irvin’s in this county. 
To convey a clearer idea of their geological relations, I subjoin the 
annexed vertical diagram; which illustrates not only the succession in 
Pulaski county, but also in Conway county:
